This build ended up working out incredibly during the last plague star event.

Reasoning behind running this:

-Move speed: Vault can speed up archwings with his 2nd ability, this combs well with high strength whisp motes as well.

-Clear time: Your 4th ability can near instantly clear a Hemocyte phase depending on a bit of RNG and your team not killing the spawn pods.

-Boss Kill: When configured for the rage buff you can cast this on the Hemocyte as it spawns to make it FLY out of the boil.

-In a group at minimum i would recommend 1 vault and person with a switch teleport setup, beyond that Whisp is incredible , 3rd choice is anything really, speedva is nice to have but really you can bring whatever you want as a 4th.

Counter to a lot of common thinking I have found that the absolute best way to clear this event is to have extremely high fire rate weapons with low base damage per projectile Ideally with high crit:

-Primary weapons i used: Cedo, Phantasma, Kohm / Kuva Kohm , Bubonico
-Secondary weapons: Pyrana Prime(still the king) , Aksomati Prime
-Melee: [Sarpa] with [Shattering Impact] and max attack speed (used to [Shred] the Hemocytes armor)
